UNITED i STATES PATENT OFFICE0 HENRY W. PEEL, OF ROME, NEW YORK.

Specification forming part of Letters Patent No. 56,602, dated July 24,1866.

To all whom it may concern: y

Be it known that I, HENRY W. PELL, of Rome, in the county of Oneida andState of New York, have invented new and useful Improvements in theManufacture of Wrenches; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying plate of drawings, forming a part of this specification.

rllhe present invention consists in subjecting a straight bar of iron,of the requisite length, width, and thickness, to the action of a seriesor set of dies, by which a head and shoulder, similar in shape to theordinary heads of wrenches, are formed thereon, and the full strength ofthe iron retained.

In accompanying plate of drawings a set of dies, by which a wrench-headis formed from and upon a bar of iron ofthe requisite dimensions, isillustrated, each die of the set being numbered upon the said plate inthe order in which they are used.

ln using-the set of dies represented in the drawings a bar of iron, ofabout two inches in width and seven-eighths of an inch in thickness andfour and a half inches in length, is iirst taken and rolled into theshape at one end (shown in Figure l of the drawings) by passing itthrough any suitable rolling-mill therefor, when, laying it on the lowerdie, A, of the iirst one of the series, it is then subjected to theaction of its upper die7 3, until sufliciently hammered thereby into ashape corresponding to such die. The bar thus hammered is then removedfrom such die and placed in the next one of the series, numbered 2 inthe drawings, and by it hammered into a shape corresponding thereto,when, removing the bar therefrom, and in turn subjecting it to the.actions of the dies numbered 3 and 4 in the drawings, the bar, whenremoved from the latter, will have the requisite head and shoulderthereon, corresponding to the ordinary wrenchheads, as is plain to beseen in the lower view of the last die, the bar of iron, however,previous to heilig' inserted in die numbered 3 in the drawings, beinglaid by its dat side upon the lower portion of die No. 1, across thenotch a of the same, and then subjected to the upper portion of the saiddie, by which it is perfect-ly prepared for dies Nos'. 3 and 4, theshape given to such bar thereby being shown in Fig. 2 of the drawings.

By thus forming a wrench-head itis obvious that the full strength of theiron is retained, and a wrench secured possessing many superioritiesover similar wrenches made in the ordinary manner.

I claim as new and desire to secure by Letters Patent- The improvementin the manufacture of wrenches herein described, the same consisting iusubjecting the bar of iron from which the wrench is to be made to theaction of the consecutive set of dies, substantially as described, andin the manner and for the purpose set forth.
